SLAB Design using STAADPro

[jacs127]

Dear Experts of the forum,

i have tried to design slab using staadpro using plate element for IS:456:2002 but surprizingly it is giving me very high %steel. Slab is of 3.5X3.5 with loaded 10 KN/sq m. For 150mm thick slab it was giving me 16mm dia steel at 100mm c/c. i was shocked to get this... any advise... i do not claim to be good structural engg but still i know slab design via hand calc...

Regards,

Jay

Hi Jacs,
Is it a flat slab or a slab for beam-slab type?? cos it depends on property of the element defined.
